[Bug]: sharded pubsub uses wrong channel after joining a room with namespace

[maitrungduc1410]

I have multiple socket io namespaces.

on client joins a specific namespace, the client will join a room under the namespace, after that server will send the client a message. Code:

ns!.on("connection", async (socket) => {
  console.log("A client connected!", socket.id);
  socket.join('Room 1')


  ns!.to(socket.id).emit("join_room_resp", {
    response: `Joined Room 1 successfully!`,
  });
});

Then I put some console.log in Redis adapter util under SPUBLISH and SSUBSCRIBE

export function SSUBSCRIBE(
  redisClient: any,
  channel: string,
  handler: (rawMessage: Buffer, channel: Buffer) => void
) {
  console.log(`>>>>>>SSUBSCRIBE ${channel}`);
  // ....
}

export function SPUBLISH(
  redisClient: any,
  channel: string,
  payload: string | Uint8Array
) {
  console.log(`SPUBLISH ${channel} ${payload}`);

  // ....
}

Output shows:

>>>>>>SSUBSCRIBE test.socket.io#/adasd#Room 1#
SPUBLISH test.socket.io#/adasd# {"type":3,"data":{"packet":{"type":2,"data":["join_room_resp",{"status":1,"room":"Room 1","response":"Joined Room 1 successfully!"}]},"opts":{"rooms":["x0jrTAQqgtKi7KDmAAAB"],"except":[],"flags":{}}},"uid":"19183eaa9eddca93","nsp":"/adasd"}

as shown above, after the user joins the channel, it subscribes Redis at channel test.socket.io#/adasd#Room 1#, but the message after that is published to channel test.socket.io#/adasd# which is wrong, and it lead to message never gets received
